livumrlx' in an impruwd mph in!) mgimy prefvz'zhh' of the mm; and mum ROTARY MOTGE LI waiting It will be observed that in each cylinder nchaniber is formed between the head of the cylinder, the cylinder wall and the outer face of the closed outer end of the piston, and another chamber is form d between the inner face of the closed ouer end of the same piston and the piston block. These chambers in the ease of an explosion engine are provided with means for admitting thereto an explosiie or working cherge, means for igniting such rlnirge and means for exhausting tlierei'rmn the burnt gases, as Will be hereafter rtipieiined.

The lnttnlleliiilt istoi'113 x1 are reciprocated Within the cylinders lay the explosions and cause through suitiihlr mechanical coir neotions from the exterior of said pistons, the rotation of the cylinders a I) regarded :ish. unit and the rotation of the aforesaid revolvii'ig nieinher upon the second fixed shaft f, both these pision moving inward or outward together, The cylinders are pro ided with inlet rind exhaust wires of the mushroom type or the inlet valves may he i'ei'ilziced by illt'illii ports isnvovercd by th sliding pi tons The valves are not shown in the dizi rzims l, and 3,

The aforesaid shafts e arr shown as a cranked shaft which i0: eecured and fixed in suitable brackets or the like. Upon one nieniher f of this cranked shaft I arrange ii flywheel or a balanced propeller adapted to be rotated on said member by means 6. g. of a, crank arm j extending outwardly from the boss of the propeller and secured thereto. Upon the other member 5 of the ornnked shaft- 1 mount the, opposed pair of cylinders a, b so that they are rotatable as a Whole thereon and I have shown provided upon said cylinders a series of levers tiuiied by the movements of the reoiproran ing pistons and connected to the above mentioned crank arm so that the reoiprocuting motions of the pistons, through the le ers carried by the cylinders and the driving crank arm, effect the rotation of the propeller simultaneously with the rotation of the, opposed cylinders. The connections between. this driving crank arm and the ,rcciprocating istons.ere shown on the draw-- ing (Figs. 1 and 2) follows: The crank arm j is secured to the head of a fork or stirrup lowhich extends from the outer end of one cylinder a and down each side of the exterior thereof. -The inner ends of these forks in /s are connected through slots] in the wall of the cylinder-with the reciprocating piston 0 therein. This may be effected by forming bosses of onthe Wall of the pieton toward the open (and of the latter and parsing transverse pin r acros the p ton (see 7i and through the bosses and securing the exterior ends of said pin to the aoresald fork arms is In this case the pin extends also through the central pistonlike hlock g which is suitably slotted for the passage of the transverse pin (3". Thus, as the piston 12 inoirs in its cylinder to or from the axis of the rotary engine it will correspondingly more the exterior fork arms )ne of these fork arms is 01% ill lur'fii beyond the pin w lending: to the piston 0 and is hinge-d or pivoted to a rod in. arranged in prolongation. of the said arm and along the some side of the second nyliiuler Z.
